A limiting long groove 26 is opened at the rear side of the safety gas mask main body 9. A limiting long hole 16 is opened on an inner side wall of the limiting long groove 26. A lace main body 1 is bonded inside the limiting long groove 26. First threaded grooves 22 and second threaded grooves 17 are respectively opened on the outer side surface of the safety gas mask main body 9. A connecting long plate 13 is fixedly connected to the top of the square hanging ring 12. Second limiting long rods 21 are fixedly connected to both the left side and the right side of the connecting long plate 13. The support long rod 11 is respectively slidably connected to the connecting long plate 13 and the second limiting long rod 21. The support long rod 11 is movably connected to the square hanging ring 12. A bolt 14 is commonly threadedly connected inside the rod body of the portal-shaped rod 15 and inside the connecting long plate 13. The bolt 14 is respectively threadedly connected to the first threaded groove 22 and the second threaded groove 17. First limiting long rods 18 are fixedly connected to both the left side and the right side of the portal-shaped rod 15. Through the settings of the safety gas mask main body 9, the hanging assembly, the first limiting assembly and the second limiting assembly, the hanging assembly can hang and store the safety gas mask main body 9, and the first limiting assembly and the second limiting assembly can both limit the hanging assembly. After the device is used, when the device needs to be hung and stored, the device can be prevented from being hung and stored through the lace main body 1, and the device can be conveniently hung and stored.
[0032] When in use, after the device is used, when the device needs to be hung and stored, rotate the bolt 14 to disconnect the bolt 14 from the first threaded groove 22 and make one end of the first threaded groove 22 located inside the connecting long plate 13. Move the portal-shaped rod 15 downward, so that the portal-shaped rod 15 slides downward along the safety gas mask main body 9, the L-shaped rod 10 and the support long rod 11 respectively, so that the first limiting long rod 18 slides downward along the L-shaped rod 10, so that the connecting long plate 13 slides downward along the safety gas mask main body 9 and the support long rod 11 respectively, so that the second limiting long rod 21 slides downward along the support long rod 11, so that the square hanging ring 12 slides downward along the safety gas mask main body 9 and the support long rod 11 respectively. When the portal-shaped rod 15 is moved downward to the maximum distance, the bolt 14 corresponds to the second threaded groove 17. Reverse-rotate the bolt 14 to threadedly connect the bolt 14 to the second threaded groove 17, so that the square hanging ring 12 protrudes from the bottom of the safety gas mask main body 9, so that the device can be hung and stored through the square hanging ring 12. At this time, the device can be hung and stored. During this process, when the device needs to be hung and stored, the device can be prevented from being hung and stored through the lace main body 1, and the device can be conveniently hung and stored.
[0033] In this embodiment, the first threaded groove 22 is located above the second threaded groove 17. The material of the limiting cone 19 is plastic, and the materials of the protection plate 2 and the protection column 3 are both silica gel.
